BALlNG-PRESSr SPECIFICATION forming part of Letters Patent No. 295,089,dated March 11, 1884,

- Application filed February 6, 1884. (N0 model.)

To (LZZ whom it satay concern:

Be it known that 1', GI'IARLES E. WHITMAN, a citizen of the UnitedStates, residing at St. Louis, State of Missouri, have invented certainnew and useful Improvements in Baling- Presses, of which the followingis a specification, reference being had therein to the accompanyingdrawings.

- My invention has reference to certain improvements in the applicationof power in horizontal billing-presses for baling hay, cotton, &c., andrelates to that class of horizontal baling-presses comprising apress-box, plunger, or traverscr, retainers, pitman, and sweep, and inwhich the plunger is thrown back in position to receive another chargeof the material to be pressed by the expansion of the pressed materialagainst the head of the plunger independent of the movement of the sweepand horse.

My improvements consist of slotted pitman, a bell-crank lever, and a lugor roll on the sweep, arranged in relation to each other,

as hereinafter described; also, in a rigid connection between theswcepand lever.

Referring to the drawings, making a part of this specification, Figure lis aperspective view of the character of press described, with myimprovements in connection therewith.

Fig. 2 is a detail of the sweep, bcll-craulc lever and pitman, andattaching staple or link, Fig. 3 shows-the bell-crank lover in twopositions.

Like letters or reference indicate co rresp onding parts in thedifferent views.

A is the sweep, to which the horse is attached by means of a single-treeorother known appliance. The sweep A is provided with a ing, a, near itsinner end, adjacent to where it revolves, or is turned on a horizontalplane on a verticai rod or shaft, A, which is secured to the top andbottom of the frame or the press. Just above the sweep, and alsoarranged to revolve on the shaft A, is a bell-crank lever, B. This leverhas an aperture at one of its sides, through which the shaft or rod Apasses. In

one of its other arms it is provided with one or a series of holes orapertures, through one of which it is pivoted to the slotted end of thepitman C, The pitmau consists of a straight arm or lever, the inner endof which is pivoted to the plunger or traverser, andthe outer end isslotted to receive one arm of the bell-crank lever. The slotted end ofthe pitman is also provided with one or more holes or aperturescorresponding with those in the arm of the lever B, and the two-leversare pivoted together by a suitable bolt or pin. By means of the twoseries of holes 1 2 or apertures, when more than one hole is used. inthe bellcrank lever B and pitman 0, they may be readily adjusted toincrease or diminish the throw of the plunger in a manner that will bereadily apparent, and thus increase or diminish the pressure against thebale, and at the same time throw the plunger or travcrser forward to thesame point. A rod, D, is attached to the sweep at one of its ends andpivoted to the top of the shaft A at the other, for the purpose of holding the sweep in a horizontal position, its tendency being to dropdownward. The bell-crank lever B is provided with an enlarged bearing,6, which holds it more firmly in position. I propose to use two of theselovers in certain instancesethat is to say, one above and one underneaththe sweep. The slot in the end of the pitman would then bedispensedwith, and

the two lovers would be pivoted to the top and bottom oi the pitmau. Thesweep would also be provided with a lug on its lower as well as itsupper side in this instance; or, if desired, one of the ends of thebell-crank lever may be slotted and the end of the pitman be insertedtherein and pivoted thereto. I deem these variations merely equivalents,and I do not restrict myself to the use of any one of them. The partsmay also be reversed by providing the bell-crank lever with lugs anddispensing with them on the sweep. The operation would be precisely thesame and wholly within the spirit of my invention.

The frame-work of the press, the form of the traverser, and theretainers shown in the drawings are well known, and I do not claim themas a part of my present invention, excepting in combination with myimprovements.

In the operation of the press, the horse is hitched to the sweep anddriven on a curved path until the sweep has made nearly a halfrevolutionin horizontal plane. hen the end of the pitman passes the vertical rodor shaft A, one of the arms of the bell-crank lever is disengaged fromthe lug, and by the expansive force of the compressed material thepitman is thrown back on the opposite side, while the sweep remainsstationary, the plunger or traverser then being in position to receivethe next charge of material to be pressed. 5 The horse is then moved inthe opposite direction and. the operation may be repeated in-.

definitely causing a continuous forward move ment of the plunger whilethe horse is in motion, thus obtaining the longest possible throw of theplunger, and at the same time moving the horse in the shortest possiblepath.

' The series of holes in the arms of the bellcrank lever and thecorresponding holes in the end of the pitman are for the purpose ofincreasing or diminishing the power, as before stated. For example, byadjusting the pitman so that its outer hole or aperture will coincidewith the inner hole of the series of the lever the greatest amount ofpower is obtained, and the plunger is nevertheless still thrown forwardto the same point, in order that the retainers may receive and hold thecompressed material.

In the operation of baling, it is apparent that until the bale is formedin the press-box sufficiently compact to throw back the plunger by itselasticity some means must be devised for this purpose. To obviate thisdifficultyin the beginning of the balin g O1)Ql'2l-l3lO1],W1161l thepress-box is empty, and until one bale is formed, I couple thebell-crank lever and sweep rigidly together.

I prefer to use the staple-shaped device 0, (shown in Fig. 2 of thedrawings,)but any other well-known means may be used. One of the lugs ofthe staple is inserted in hole inone 'arm of the bell-crank lever, andthe other lug in a hole in the sweep. As soon as a bale is formed, asbefore stated, the staple or link is 40 removed, and the'plungeristhereafter thrown back by the expansive force of the pressed material.

A stop, X, may, if desired, be placed on the base of the press-box toprevent the traverser from rebounding too freely.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1.' In a horizontal bailing-press, the combination of a bell-crank leverwith a pitman, 5o traverser, sweep, and press-box, substantially asdescribed.

2. In a horizontal baling-press, the combination of the slotted pitmanwith the trav erser, bell-crank lever, and sweep, substan- 5 5 tially asdescribed.

3. In a horizontal baling-press, the combination of the sweep providedwith a lug or lugs, bell-crank lever or levers, or the equivalentthereof, as set forth, with the pitman and traverser, substantially asdescribed.

4. In a horizontal baling-press, the combination of a bell-ferank leverprovided in one of its arms with series of holes or apertures,

a pitman also provided with a series of holes, and a suitable connectingpin or bolt for increasing or diminishing the power, and yet advancingthe traverser to the same point, substantially as set forth.

5. In a horizontal billing-press, a connect- 7o ing-link between thebell-crank lever and sweep, for securing them rigidly together at thecommencement of the baling operation, substantially as described. v

In testimony whereof I affix my signature in 7 5 presence of twowitnesses.
